The seatbelt syndrome represents an injury pattern seen after motor vehicle accidents. It is secondary to either the misplacement of seatbelts over the abdomen or the misuse of the restraint systems. This syndrome is infrequent in the pediatric population and occurs mostly in school-aged children because recommended lap-shoulder belts and booster seats are often not used in this age group, so that the seatbelt lies over the abdomen. Sudden deceleration bends the child around the lap belt causing injuries to the viscera, head, and spine (Chance fracture), often associated with paraplegia. Because not all patients have an abdominal seatbelt sign, this syndrome can easily not be recognized with potentially life-threatening consequences.We report on 3 patients with the seatbelt syndrome and review the literature regarding prevalence, diagnosis, treatment, and prognosis of the different injuries and discuss the diagnostic challenges of intestinal lesions and their management.Following this accident pattern, in hemodynamically stable patients with a normal abdominal computed tomography scan, close surveillance is warranted to rule out intestinal lesions manifesting with progressive peritoneal irritation. In hemodynamically unstable patients, or if there is evidence of free air on the computed tomography scan, emergency abdominal exploration is required.

The use of tissues of porcine origin has gained significant momentum in the scientific community due to their anatomical and physiological resemblance to human tissues. This review provides a comprehensive overview of the key biological features of porcine ocular structures, including the cornea, conjunctiva, and associated tissues, in comparison to their human counterparts. Additionally, this review outlined the ex vivo applications of these tissues in the study of different biological processes and the simulation of pathological conditions.

With the rapid development of nanotechnology, nanoultrasonography has emerged as a promising medical imaging technique that demonstrates significant potential in the diagnosis and treatment of gastrointestinal (GI) diseases. This review discusses the applications of nanoultrasonography in the gastrointestinal field, including improvements in imaging resolution, diagnostic accuracy, latest research findings, and prospects for clinical application. By analyzing existing literature, we explore the role of nanoultrasonography in enhancing imaging resolution, enabling targeted drug delivery, and improving therapeutic outcomes, thereby providing a reference for future research directions.

Severe combined immunodeficiency disease (SCID), characterized by profound immune system dysfunction, can lead to life-threatening infections and death. Animal models play a pivotal role in elucidating biological processes and advancing therapeutic strategies. Recent advances in gene-editing technologies, including zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), CRISPR/Cas9, and base editing, have significantly enhanced the generation of SCID models.

Background: Computed tomography (CT) is the gold standard imaging modality for the assessment of 3D bony morphology but incurs the cost of ionizing radiation exposure. High-resolution 3D magnetic resonance imaging (MRI) with CT-like bone contrast (CLBC) may provide an alternative to CT in allowing complete evaluation of both bony and soft tissue structures with a single MRI examination.
Purpose: To review the technical aspects of an optimized stack-of-stars 3D gradient recalled echo pulse sequence method (3D-Bone) in generating 3D MR images with CLBC, and to present a pictorial review of the utility of 3D-Bone in the clinical assessment of common musculoskeletal conditions.
